75c6a925da Revert ABI changes to std::allocator in C++20 
The recent C++20 changes to remove the std::allocator<void> explicit
specialization and the destructor in the std::allocator primary template
change the result of some is_trivially_xxx type traits. To avoid those
changes, this patch restores the explicit specialization and the
destructor.

In order to meet the C++20 requirements the std::allocator<void>
explicit specialization must provide the same interface as the primary
template (except for the unusable allocate and deallocate member
functions) and the destructor in the primary template must be constexpr.

	* include/bits/allocator.h (allocator<void>): Restore the explicit
	specialization for C++20, but make its API consistent with the primary
	template.
	(allocator::~allocator()): Restore the destructor for C++20, but make
	it constexpr.
	* testsuite/20_util/allocator/rebind_c++20.cc: Check allocator<void>.
	* testsuite/20_util/allocator/requirements/typedefs_c++20.cc: Likewise.
	* testsuite/20_util/allocator/void.cc: Check that constructors and
	destructors are trivial. Check for converting constructor in C++20.
	* testsuite/ext/malloc_allocator/variadic_construct.cc: Simplify
	dejagnu target selector.
	* testsuite/ext/new_allocator/variadic_construct.cc: Likewise.

2cae56bd61 Remove redundant std::allocator members for C++20 
C++20 removes a number of std::allocator members that have correct
defaults provided by std::allocator_traits, so aren't needed.

Several extensions including __gnu_cxx::hash_map and tr1 containers are
no longer usable with std::allocator in C++20 mode. They need to be
updated to use __gnu_cxx::__alloc_traits in a follow-up patch.

	* include/bits/alloc_traits.h
	(allocator_traits<allocator<T>>::allocate): Ignore hint for C++20.
	(allocator_traits<allocator<T>>::construct): Perform placement new
	directly for C++20, instead of calling allocator<T>::construct.
	(allocator_traits<allocator<T>>::destroy): Call destructor directly
	for C++20, instead of calling allocator<T>::destroy.
	(allocator_traits<allocator<T>>::max_size): Return value directly
	for C++20, instead of calling std::allocator<T>::max_size().
	(__do_alloc_on_copy, __do_alloc_on_move, __do_alloc_on_swap): Do not
	define for C++17 and up.
	(__alloc_on_copy, __alloc_on_move, __alloc_on_swap): Use if-constexpr
	for C++17 and up, instead of tag dispatching.
	* include/bits/allocator.h (allocator<void>): Remove for C++20.

c787deb012 skip Cholesky decomposition in is>>n_mv_dist 
normal_mv_distribution maintains the variance-covariance matrix param
in Cholesky-decomposed form.  Existing param_type constructors, when
taking a full or lower-triangle varcov matrix, perform Cholesky
decomposition to convert it to the internal representation.  This
internal representation is visible both in the varcov() result, and in
the streamed-out representation of a normal_mv_distribution object.

The problem is that when that representation is streamed back in, the
read-back decomposed varcov matrix is used as a lower-triangle
non-decomposed varcov matrix, and it undergoes Cholesky decomposition
again.  So, each cycle of stream-out/stream-in changes the varcov
matrix to its "square root", instead of restoring the original
params.

This patch includes Corentin's changes that introduce verification in
testsuite/ext/random/normal_mv_distribution/operators/serialize.cc and
other similar tests that the object read back in compares equal to the
written-out object: the modified tests pass only if (u == v).

This patch also fixes the error exposed by his change, introducing an
alternate private constructor for param_type, used only by operator>>.

transformation still uses the same underlying std::tr1::array<T, 1>
array, which may not be correctly aligned or even have elements the

It has been deprecated for several years and should now be removed.

78ed0f80c3 Fix tests that use allocators with incorrect value types 
As a GNU extension we allow containers to be instantiated with
allocators that use a different value type from the container, and
automatically rebind the allocator to the correct type. This extension
is disabled in strict modes (when __STRICT_ANSI__ is defined, i.e.
-std=c++NN dialects). These testcases unintentionally rely on the
extension and so fail for strict modes.

Tests which intentionally make use of the extension will still fail in
strict dialects, but will be addressed in a later change.

c7790bdbd9 Make ext allocators support heterogeneous equality comparison 
The Allocator requirements include the ability to compare different
specializations of the same allocator class template. This did not work
for __gnu_cxx::new_allocator and other extension allocators.  This patch
replaces the equality operators for those allocators with inline friends
that support heterogeneous comparisons.  (I'm not changing all ext
allocators because some are bit-rotted already).

Additionally, the equality operators for comparing two std::allocator
objects of the same type are now defined as inline friends. Those
overloads don't need to be declared at namespace scope, because they
aren't specified in the standard (but they're needed in this
implementation to avoid ambiguities caused by the extra overloads
defined for the base allocator type).

3ffa55de60 Rope iterators: don't retain pointers when copied 
Rope iterators sometimes contain pointers to an internal buffer
inside the iterator itself.  When such an iterator is copied, the
copy incorrectly retains pointers to the original.

This patch takes the simple approach of not copying the cached
information when the internal buffer is being used, instead
requiring it to be recomputed when the copied iterator is
dereferenced.  An alternative would be to adjust the pointers so
they refer to the buffer in the copy.
